Fantastic! Finally some hardware debouncing! This would make a perfect mailbox alert system as well right? If a little overkill perhaps.

Do you know of any integrated hardware debouncer solutions besides going for schmitt triggers? (that are affordable!) I did look at the MAX6816/MAX6817/MAX6818 (https://www.maximintegrated.com/en/products/interface/circuit-protection/MAX6818.html) series myself, but I never got around to using them, and they aren't super cheap exactly and only operate from 2.7V. Surely there must be other manufacturers doing similar ICs?

@bjornhallberg
Unfortunately I couldn't find cheap initegrated debouncer. :( More over - I don't need ordinary debouncer, I need debouncer + edge detector for each channel (to hook 0->1 and 1->0 transitions).

Very nice! The next revision to https://www.openhardware.io/view/48/Homini-In-Wall-Battery-Powered-Light-Switch-Module will attempt to get smaller much like yours here. I use a nRF24L01+ for my communication and will need to attempt to get this flat on the board to make my footprint any thinner. Thank you for the inspiration!

And after mounting :)

Oh.. Earlier I received cr2032 holders instead of cr2450. And now I've received cr2477 instead of cr2450... It's better, because it's possible to cut holders so they can be compatible with cr2450 battery :stuck_out_tongue:

And I'm ready to start mass testing :smiley:

[Samuel235]

Very nice, super professional finish to those board, nice work dude! I'm very interested in the way you have the power supply. I may just learn a few things from you and apply to my modules! Thank you!

I've added SPI flash for OTA on this board too. And I've replaced 0402 components to 0603 so this board becomes not so crazy :grinning:

[vikasjee]

Fantastic! Can i buy it pre-assembled from somewhere?

[vikasjee]

Great! Which is the one with the transformer? any link to it?

[yury]

We are changing PCBA contractor which is supposed to assemble Koresh projects. Since current one gave us way too many errors while assembling other projects for our "Day Job" we work with Koresh together. so may be some delay for all Koresh projects.

Hello
Will you build an nrf24l01 smd version ?

[blacey]

Interesting board. While you have designed this to be a wall-insertable board, one could envision packaging this into a small case with 4 buttons attached to the surface for a portable scene controller/remote. Well done!

[Cliff Karlsson]

Is it possible to buy this board assembled from you now?

[Koresh]

@Cliff-Karlsson
Hope the batch of assembled boards (latest version after all fixes) will be ready in a week.

[Sander Teunissen]

@koresh Great to hear you have assembled components available! I am following your other projects too (like the usb dongle and switchable power supply) .Will these become available as assembled components too ?

[Koresh]

Board works with nrf24 too :wink:

[Samuel235]

@Koresh - Do you happen to have a link for the JST connectors? I can't seem to find any at a reasonable price at the moment. And the male side too, if you don't mind me asking :)

The price depends on a batch size. You can try to ask any supplier on ali for 100-200 pcs and may be price will be reasonable :)
